Aristotle's Wheel Paradox - How Can This Be Possible?
- How can 2 wheels of different diameter both turning one complete revolution travel exactly the same distance
- This paradox is nicely demonstrated using this wood model. Aristotle took a whack at this in the Aristotelian Mechanica, as well as in the Mechanica of Hero of Alexandria and Galileo gave it a try as well.
- Designed and made in USA by Creative Crafthouse, a small family business in Hudson, FL. Thank you for your support.

- How Can This Be Possible? - An ancient paradox demonstrted through this wood model
- Did Aristotle Invent This Paradox? - Not everyone agrees he is the inventor, but tend to agree this would be right up his ally
- See below for a more in depth description of this interesting and mind boggling paradox
How can 2 wheels of different diameter both turning one complete revolution travel exactly the same distance? This paradox is nicely demonstrated using this wood model. Aristotle took a whack at this in the Aristotelian Mechanica, as well as in the Mechanica of Hero of Alexandria and Galileo gave it a try as well. The paradox involves two different-sized wheels, one inside another. The two rotate in sync and you can see as you turn the wheels to travel the length of the opening in the puzzle that the etched line on the wheels turns one time, thus the circumference of each wheel has rotated over an equal length. Both wheels use exactly one circumference to trace the same amount of distance - the length of the space in the puzzle. But, clearly one circumference is smaller than the other. Either that means that the wheels have the same circumference, which they don't, or that different circumferences "unroll" to the same length, which they can't. That can't possibly be right.... The smaller radius can't possibly be equal to the larger one, so what's going on? To further illustrate the paradox, I have included an separate copy of the inner wheel. We know that when attached to the bigger wheel that it turns one rotation to cover the length of the opening starting at the hash mark. But now take the small wheel and position it at the same starting point and rotate one revolution.... it does not travel the same distance! Such a dilemma.... Can you explain it??
